How can I modify the download progress bar in the YouTube Video Downloader template to show real download progress?
To modify the download progress bar to show real download progress, you'll need to implement server-side functionality to handle the actual download and send progress updates to the client. Here's a basic example of how you could modify the home.js
file to receive real progress updates:
```javascript document.addEventListener('DOMContentLoaded', () => { const form = document.getElementById('download-form'); const progressBar = document.getElementById('progress-bar'); const progressText = document.getElementById('progress-text'); const downloadProgress = document.getElementById('download-progress');
form.addEventListener('submit', async (e) => {
e.preventDefault();
const videoUrl = document.getElementById('video-url').value;
const format = document.querySelector('input[name="format"]:checked').value;
if (!videoUrl) {
alert('Please enter a YouTube video URL');
return;
}
downloadProgress.classList.remove('hidden');
try {
const response = await fetch('/api/download', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ videoUrl, format })
});
const reader = response.body.getReader();
const contentLength = +response.headers.get('Content-Length');
let receivedLength = 0;
while(true) {
const {done, value} = await reader.read();
if (done) break;
receivedLength += value.length;
const progress = Math.round((receivedLength / contentLength) * 100);
progressBar.style.width = `${progress}%`;
progressText.textContent = `Downloading... ${progress}%`;
}
progressText.textContent = 'Download complete!';
} catch (error) {
console.error('Download failed:', error);
progressText.textContent = 'Download failed. Please try again.';
}
});
}); ```
This code assumes you have a server-side API endpoint at /api/download
that handles the actual video download and streams the response.

Here's a step-by-step guide for using the YouTube Video Downloader template:
Introduction
This template provides a simple web application for downloading YouTube videos as either MP4 (video) or MP3 (audio) files. It features a user-friendly interface where users can input a YouTube video URL and select their preferred download format.
Getting Started
- Click "Start with this Template" to begin using the YouTube Video Downloader template in the Lazy Builder interface.
Test the Application
- Press the "Test" button in the Lazy Builder interface to deploy the application and launch the Lazy CLI.
Using the YouTube Video Downloader
-
Once the application is deployed, Lazy will provide you with a dedicated server link to access the web interface.
-
Open the provided link in your web browser to access the YouTube Video Downloader interface.
-
On the web interface, you'll see a form with the following elements:
- An input field to paste the YouTube video URL
- Radio buttons to select the desired format (MP4 or MP3)
-
A "Download" button to initiate the download process
-
To use the downloader:
- Paste a valid YouTube video URL into the input field
- Select your preferred format (MP4 for video, MP3 for audio)
-
Click the "Download" button
-
The application will display a progress bar simulating the download process. Once complete, you'll see a "Download complete!" message.
Important Notes
- This template provides a mock download experience for demonstration purposes. To implement actual YouTube video downloading functionality, you would need to integrate a YouTube downloading library and handle the download process server-side.
- Ensure you comply with YouTube's terms of service and copyright laws when implementing and using video downloading features.
By following these steps, you'll have a functional YouTube Video Downloader interface up and running using the Lazy platform. Remember that this template serves as a starting point, and you may need to extend its functionality for a production-ready application.
